Begomoviruses (family Geminiviridae) constitute the largest genus in the virosphere in terms of number of species and are exclusively transmitted by whiteflies of the Bemisia tabaci species complex in a persistent manner. These viruses circulate in the insect body, from the gut lumen into the hemolymph or other tissues and finally into the primary salivary glands, from where the viruses are introduced back into the plant host during insect feeding, and complex interactions between virus and vector components are involved in this process. Whether this group of viruses can replicate within B. tabaci has received constant attention given the great importance of virus evolution and epidemiology. While several articles have reported replication of tomato yellow leaf curl virus (TYLCV), one of the most devastating begomovirus that has caused tremendous losses to tomato, tobacco and other crops worldwide, other articles have reported the contrary. Discussions of this disparity have been going in the science community for the last 2-3 decades. In an attempt to examine this disparity, my current studies focus on whether begomoviruses can replicate in their whitefly vectors, the possible replication sites and the mechanisms involved in this process. In addition, I have studied the transovarial transmission of begomoviruses by the B. tabaci.

I graduated from Huazhong Agricultural University in 2014 with a BSc degree in Plant Science and Technology. During my BSc study, I joined the research on protoplast regeneration and rejuvenation of Poria cocos (Schw.) Wolf, a medicinal mushroom in Chinese medicine.
